How to Clean a Cat's Ears: Safe Steps, Wax, Mites and Infections

By Tailwisp Editorial TeamUpdated October 20, 20264 min read

Cat ears are self-cleaning in most cases, with small amounts of wax moving outward naturally. Over-cleaning can do more harm than good, but sometimes ears need help, and sometimes the debris is a sign of something that needs treatment. Knowing the difference keeps your cat comfortable.

What a healthy ear looks like

A healthy cat ear is pale pink inside, with a small amount of light-colored wax, no strong odor and no redness or swelling. The cat does not shake its head or scratch its ears excessively. Some breeds with large or hairless ears, such as the Sphynx and the Devon Rex, accumulate more wax and may need regular, gentle cleaning.

Signs of a problem

Contact your vet if you see:

• Dark, crumbly debris resembling coffee grounds, typical of ear mites
• Yellow, green or bloody discharge
• A strong, yeasty or foul odor
• Redness, swelling or heat in the ear
• Frequent head shaking or scratching, sometimes causing scabs
• A head tilt, loss of balance or abnormal eye movements
• Pain when the ear is touched
• A swollen ear flap, which may indicate a hematoma

These signs mean infection, mites, allergies, polyps or other conditions. Cleaning alone will not fix them, and medication may be needed. See the emergency warning signs guide for neurological signs that need urgent care.

What you need

• A veterinarian-approved cat ear cleaner
• Cotton balls or gauze squares
• Treats
• A towel
• A helper if your cat is wiggly

Do not use cotton swabs in the canal, hydrogen peroxide, rubbing alcohol, vinegar or oils. They can irritate delicate tissue or leave moisture that promotes infection.

How to clean the ears

1. Choose a calm time. After a meal or play is ideal.
2. Hold your cat securely, in your lap or wrapped in a towel, with the head steady.
3. Lift the ear flap gently and squeeze a few drops of cleaner into the canal, following the product's instructions.
4. Massage the base of the ear for about 20 to 30 seconds. You will hear a squishing sound.
5. Let the cat shake its head, which brings debris to the surface.
6. Wipe the outer ear with a cotton ball or gauze, removing visible debris. Do not dig into the canal.
7. Reward with a treat and praise.

If your cat resists strongly, stop. Forcing the issue can injure the ear and make future cleaning harder.

Ear mites

Ear mites are tiny parasites that live in the ear canal, spread between cats and sometimes dogs, and are more common in kittens and outdoor cats. They cause intense itching, dark debris and head shaking. Your vet can confirm mites with a microscope and prescribe a treatment that is safe for your cat. Over-the-counter products are not always effective, and some are not safe for kittens. Treat all pets in the home as advised.

Infections and other causes

Bacterial and yeast infections often follow mites, allergies or moisture. Polyps, foreign bodies such as grass seeds and tumors are other causes. A vet exam with an otoscope can find the cause and select proper treatment. Untreated ear disease can damage hearing and spread to the middle ear. See cat vet visit costs for typical expenses.

Ear hematoma

Vigorous head shaking can burst small blood vessels in the ear flap, forming a swollen, soft hematoma. It needs veterinary care, and the underlying cause of the shaking should be treated.

Prevention

• Check ears weekly, during brushing. See how to brush a cat.
• Keep outdoor cats on parasite prevention advised by your vet.
• Keep ears dry after baths.
• Treat allergies and skin problems early.
• Regularly examine breeds with big or hairless ears.

White cats and deafness

White cats with blue eyes can be deaf, and ear problems may be harder to notice. If your cat does not respond to sounds, ask your vet about hearing tests. See the Turkish Angora profile for notes on living with a deaf cat.

Cleaning kittens and nervous cats

Kittens often tolerate ear handling well if it starts early. Touch the ears gently during cuddles, reward calm behavior and keep sessions to a few seconds. For nervous adult cats, wrap the body in a towel with only the head showing, work in a quiet room and clean one ear at a time, taking a break between them. If your cat becomes frantic, a veterinary nurse can do the cleaning for you and show you the technique. Never clean the ears of a cat that is in obvious pain, since an inflamed ear can be extremely tender and may need medication first.

Keeping a record

Take a photo of the ears when they are healthy, so that you can compare when something changes. Note the date, color and amount of any debris, and share the photos with your vet. This makes it easier to tell whether a problem is getting better or worse over several days.

When to see a vet

Any ear with discharge, odor, redness or pain, or any cat that shakes its head repeatedly, needs an exam. Use the US vet directory to find a clinic.
